Multioxide Nanomaterials Zn, Cu, and Mn: Combining Nanozyme and Photocatalyst Functions for Environmental Applications
Year: 2025
Type: article
Abstract: The study analyses nanotechnology advances in the synthesis of catalytic nanozymes that mimic enzymatic properties but are also inorganic nanomaterials. It compares Zn-Mn-Cu multioxide and Mn-Cu multioxide nanomaterials in terms of the role of nanozymes and photocatalysts in the decomposition of trypan blue dye. The study showed that Zn-Mn-Cu multioxide nanoxide has activity as a peroxidase-like nanozyme (100 mUnit/mL) and achieves 75% dye degradation as a photocatalyst under UV light. At the same time, Mn-Cu multioxide shows enhanced photocatalysis under visible light (45% degradation), consistent with its biocatalytic-like hydrolysis mechanism. In addition, both materials showed biocatalytic-like activity in the degradation of trypan blue dye (25%), without an additional light source. Further investigation of these dual nanozyme activities may reveal novel solutions for environmental photocatalysis.
